Abstract

An apparatus includes a processor and memory storing executable computer program code causing the apparatus to at least receive requests from communication devices or applications, a request of the requests associated with requester credentials; analyze instances of data of the requests based at least in part on a comparison of the requester credentials and credentials of a creator of the instances of data; generate an index based at least in part on the analysis of the instances of data of the requests, wherein the index comprises an instance of type access control determined based at least in part on the comparison; and automatically generate a data model, in a development environment, based at least in part on data in the index, the data model comprises definitions defining access control for instances of data designated for validation of received instances of data. Corresponding methods and computer program products are also provided.

Claims

1. A method comprising:

receiving one or more requests from one or more communication devices or one or more applications, a request of the one or more requests associated with requester credentials;

analyzing one or more instances of data of the requests based at least in part on a comparison of the requester credentials associated with the request and credentials of a creator of the one or more instances of data;

generating at least one index based at least in part on the analysis of the one or more instances of data of the requests, wherein the at least one index comprises at least one instance of type access control determined based at least in part on a result of the comparison;

automatically generating, via a processor, a data model, in a development environment, based at least in part on the data in the index, the data model comprises one or more definitions defining access control for instances of data designated for validation of one or more received instances of data; and

validating the one or more received instances of data within the development environment based at least in part on the generated data model and in response to detecting the generated data model.

2. A method according to claim 1 further comprising specifying a time period for retrieval of a subset of the data, in the index, that was included in the index during the time period.

3. A method according to claim 1, wherein at least one of the one or more requests is an Update, Delete, or Get request.

4. A method according to claim 1 further comprising, in response to determining that the requester credentials are different from the credentials of the creator of the one or more instances of data, deriving access control for instances of data depending on an operation of the request.

5. A method according to claim 1 further comprising, in response to determining that the requester credentials are similar to the credentials of the creator of the one or more instances of data, determining access control for instances of data of the requests is private.

6. A method according to claim 1 wherein validating the one or more received instances of data received from the one or more communication devices or the one or more applications is based in part on analyzing one or more definitions of the generated data model to determine whether the received instances of data comply with the definitions of the generated data model.

7. A method according to claim 1, wherein prior to validating, the method further comprises:

activating validation of one or more types of instances of data in the development environment in response to detection of the generated data model.

8. A method according to claim 1, wherein the access control is selected from a group consisting of public, private, and group access control.

9. An apparatus comprising:

at least one processor; and

at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

receive one or more requests from one or more communication devices or one or more applications, a request of the one or more requests associated with requester credentials;

analyze one or more instances of data of the requests based at least in part on a comparison of the requester credentials associated with the request and credentials of a creator of the one or more instances of data;

generate at least one index based at least in part on the analysis of the one or more instances of data of the requests, wherein the at least one index comprises at least one instance of type access control determined based at least in part on a result of the comparison;

automatically generate a data model, in a development environment, based at least in part on the data in the index, the data model comprises one or more definitions defining access control for instances of data designated for validation of one or more received instances of data; and

validate the one or more received instances of data within the development environment based at least in part on the generated data model and in response to detecting the generated data model.

10. An apparatus according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to perform at least:

specify a time period for retrieval of a subset of the data, in the index, that was included in the index during the time period.

11. An apparatus according to claim 9, wherein at least one of the one or more requests is an Update, Delete, or Get request.

12. An apparatus according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to perform at least:

in response to determining that the requester credentials are different from the credentials of the creator of the one or more instances of data, derive access control for instances of data depending on an operation of the request.

13. An apparatus according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to perform at least:

in response to determining that the requester credentials are similar to the credentials of the creator of the one or more instances of data, determine access control for instances of data of the requests is private.

14. An apparatus according to claim 9, wherein to validate the one or more instances of received data received from the one or more communication devices or the one or more applications, the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to perform at least analyze one or more definitions of the generated data model to determine whether the received instances of data comply with the definitions of the generated data model.

15. An apparatus according to claim 9, wherein prior to validating the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to perform at least:

activate validation of one or more types of instances of data in the development environment in response to detection of the generated data model.

16. An apparatus according to claim 9, wherein the access control is selected from a group consisting of public, private, and group access control.

17. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

program code instructions configured to receive one or more requests from one or more communication devices or one or more applications, a request of the one or more requests associated with requester credentials;
